Guhring 304198225 30mm 475.0 x 332.0 HSS Stiftlochbohrer Twist Drill Bit

This is a new Gühring 304198225 Stiftlochbohrer (pin-hole / dowel-hole drill), catalog item number 23571115, manufactured in Germany to Gühring's precision standards. The drill is HSS (High Speed Steel) construction with a black oxide surface treatment, 30.0 mm cutting diameter as engraved on the shank, an overall length of 475 mm, and a flute / working length of 332 mm as indicated on the original packaging label. The cylindrical shank incorporates a Morse-taper-style stepped reduction with an internal coolant port visible at the shank end face, making it suited for deep-hole pin-bore and dowel-bore operations on machining centers and drill presses equipped with appropriate collet or chuck toolholding. The Stiftlochbohrer geometry features an aggressive helix angle and chip-clearing flute profile designed for deep, precise bores in steel and cast materials. The tool is supplied in its original Gühring protective tube, unused and unsharpened.
